Problems solved by technology

[0003] The existing navigation system software has complicated operation and bloated functions in software design; there are many manual steps in user operation, low execution efficiency, and high error rate
Moreover, the existing technology is not intelligent enough to process lesion images, and the accuracy is low
The above makes it difficult to obtain accurate projection of the lesion, which makes the surgical navigation system unable to be applied to the actual surgical process on a large scale

Embodiment 1

[0032] This embodiment provides a surgical navigation system based on lesion image projection. The surgical navigation system includes: an image processing module, an image fusion module, a three-dimensional reconstruction module and a surface acquisition module.

[0033]Specifically, the above four modules perform data interaction through the software core control system, and call various databases (such as image fusion algorithm database, image calibration algorithm database, machine vision algorithm database, etc.) through the software core control system, such as figure 2 Shown is a schematic diagram of a surgical navigation system.

[0034] The image fusion module is configured to fuse the pre-acquired first CT lesion image and the first MRI lesion image according to the image fusion algorithm database to obtain the first lesion image.

[0035] Specifically, the function of the image fusion module here is to display the different contents of different medical images (CT...

Embodiment 2

[0051] This embodiment provides another surgical navigation system based on lesion image projection. The surgical navigation system includes: a core layer, a functional layer, and an application layer; the core layer includes a software core control system, an image fusion algorithm database, an image calibration algorithm database, and a machine vision algorithm database; the functional layer includes an image processing module and an image fusion module. , 3D reconstruction module, surface acquisition module, codec module and data security module; the application layer includes: function interaction module, independent image display module, help and reminder module and system setting module, such as image 3 shown.

[0052] Specifically, the main function of the core layer is to provide precise control and real-time computing work for the functional layer. The core control system of the software at the core layer is the center of the software, providing communication betwee...

Embodiment 3

[0086] An embodiment of the present invention provides a surgical navigation method based on lesion image projection, such as Figure 4 As shown, the surgical navigation method includes:

[0087] Step S402, according to the image fusion algorithm database, the pre-acquired first CT lesion image and the first MRI lesion image are fused to obtain the first lesion image.

[0088] Step S404, adjusting the image quality of the first lesion image to obtain a second lesion image; wherein, the second lesion image is a two-dimensional image.

[0089] Step S406, performing three-dimensional splicing and combination on multiple second lesion images to obtain a third lesion image; wherein, the third lesion image is a three-dimensional image.

[0090] Step S408, collecting the real image of the patient's current diseased part, and correcting the real image according to the machine vision algorithm database to obtain the corrected real image.

[0091] In step S410, the third lesion image ...

Abstract

The invention provides a surgical navigation system and method based on focus image projection, and an image fusion module of the surgical navigation system is used for fusing a CT focus image and a nuclear magnetic focus image according to an image fusion algorithm database, a three-dimensional reconstruction module used for performing three-dimensional splicing combination on the plurality of focus images, a surface acquisition module used for acquiring and correcting a real image of a current diseased part of the patient, and an image processing module used for mixing the processed focus image and the corrected reality image, and correcting the two-dimensional image by using the mixed image, so that the corrected two-dimensional image is used for navigation for an operation. According to the technology, through image fusion, image reconstruction and image correction, the matching degree of a focus image and an actual operation is improved; by simplifying unnecessary operation of a user, the use efficiency is improved, and the operation preparation time is shortened.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a surgical navigation system and method based on lesion image projection. Background technique [0002] The surgical navigation system is a medical device with a high degree of specialization in surgical operations. It includes two parts, software and hardware. The software drives the hardware to operate the device, so as to achieve the purpose of assisting surgery. [0003] The existing navigation system software has complex operations and bloated functions in software design; there are many manual steps in user operations, low execution efficiency, and high error rate in use. Moreover, the prior art is not intelligent enough to process lesion images, and the accuracy is low. The above makes it difficult to obtain accurate projection of the lesion, which makes the surgical navigation system unable to be applied to the actual surgical process on a large scale.
